Brammer build up cost savings for Hanson

Innovative fan drive motor solution boosts energy savings and reduces payback time at Whittlesey brick works

AN innovative solution from Brammer, the UK’s leading distributor of industrial maintenance, repair and overhaul (MRO) products and services, has helped Hanson Building Products to achieve an annual cost saving of nearly £24,000.

Hanson were keen to reduce energy consumption at their brick manufacturing facility at Whittlesey, in Cambridgeshire, with the company believing that fitting a new IE2 motor to a fan drive would reduce component stress and cut electricity bills too.

However, having been called in to review the application, Brammer proposed the installation of a new energy-efficient Siemens IE3 motor, Poly Chain transmission and Siemens inverter.

These new inclusions to the fan drive would allow the motor speed to be reduced by 10% without any compromise on output, delivering an energy saving of £8,000 per year, with a total payback time of eight months.

Once the system had been installed, however, it was found that a speed reduction of 29% could be achieved without impacting on the required airflow. This delivered a total energy saving equal to £23,650 per year, with a total payback time of less than three months.

Lee Bridge of Hanson Building Products said: ‘This was an application where Brammer’s proactivity and analytical thinking delivered a far bigger saving than we originally believed was achievable.

‘Like all manufacturers, we are always seeking ways to reduce energy consumption and Brammer, through their independent expertise and ability to recommend and supply a full range of energy-efficient products, have a major role to play in that.’

Andy Hickin, regional key account executive at Brammer, added: ‘This is one of a number of projects on which Brammer and Siemens have collaborated to deliver drivetrain optimization for customers, using the combined expertise of each company to help improve production efficiency.’
